wifi ativo mas não lista redes
Boa noite,
meu notebook HP com Mint 18 estava funcionando normalmente mais cedo, e agora não conecta no wifi. O wifi está ativo mas não lista as redes. Procurei post semelhantes e não encontrei uma solução, mas usei os comandos sugeridos nos posts e postei abaixo para me ajudarem a entender o que pode estar acontecendo.
